INTRODUCTION Danish centers reserve longer time for screening colonoscopies and allocate the most experienced endoscopists to these cases. The objective of this study is to determine the diagnostic yield in colonoscopies for different indications to improve planning of colonoscopy activity and allocation of the highly skilled endoscopists. METHODS Nine hundred and ninety-nine randomly collect...
This study assessed the first year of a regional general practitioner (GP) open-access neuroimaging service, to determine diagnostic yield and influence on patient management. Overall, 48.1% of examinations demonstrated a radiologically significant abnormality with 64.1% of spinal imaging examinations demonstrating significant findings. Utilised appropriately, a regional open-access neuroimagin...
Background In current practice, the diagnostic yield of endomyocardial biopsy is low because the procedure is performed ‘blind’ using X-ray fluoroscopy guidance and because many pathologies affect the myocardium in a patchy distribution. We hypothesized that biopsy performed under direct realtime MRI guidance would have superior diagnostic yield, in an animal model of focal myocardium pathology.
INTRODUCTION AND OBJECTIVES The evaluation of pleural effusion (PE) includes various techniques, including pleural biopsy (PB). Our aim was to study the diagnostic yield of Tru-Cut needle PB (TCPB) and to define clinical/radiological situations in which TCPB might be indicated as an initial procedure. METHODOLOGY Retrospective study of TCPB in a hospital centre (2010-2012). Cases of pleural l...
BACKGROUND AND AIMS The ability to safely and effectively obtain sufficient tissue for pathologic evaluation by using endoscopic ultrasound (EUS) guidance remains a challenge. Novel designs in EUS needles may provide for improved ability to obtain such core biopsies. The aim of this study was to evaluate the diagnostic yield of core biopsy specimens obtained using a novel EUS needle specificall...
INTRODUCTION Fluoroscopy-guided bronchoscopy is usually performed for the diagnosis of peripheral pulmonary lesions (PPL), but the diagnostic yield varies widely among studies. Endobronchial ultrasound (EBUS) can increase the diagnostic yield of bronchoscopic diagnosis of PPL. OBJECTIVE To compare the diagnostic yield of fluoroscopy-guided bronchoscopy and EBUS with fluoroscopy-guided broncho...
